WICK-CLEANING ATTACH ENT FOR. LiQUIn-FuEL BURNE'RS.

To all whom it may concern:

Be it known that We,-ERNEST M. FREoK and FRANK V. ROBERTS, citizens of the United States, residing at Asheville, in the county of Buncombe and State of North Carolina, have invented certain new and useful Improvements in Wickfileaning Attachments for Liquid- Fuel Burners, of which the following is a specification.

This invention relates to wick cleaning appliances forliquid fuel burners and has as its primary object to provide a wick which will permit of the wicks of a blue flame oil stove or liquid fuel burners of other types being readily cleaned without the necessity of removingjany of the burner parts and wiping ofl'the edge of the wick as is at present necessary and which operation not only requires time but also re,- sults .in soiling of ones hands. Whilethe device embodying the present inventionis designed more particularly as an attachment for the burners of blue flame oil stoves Which are now in use and is adapted for ap plication topractically any of'the ordinary types of such burners, it will be understood, of course, tion may find embodiment directly in the initial construction of'suchburners.

The present invention also hasasits object to provide a device for the purpose stated the presence of'which in the burner structure will not in any way interfere with removal of the flame spreaderor any other of the detachable parts of the burner, the cleaning member of the device being in fact removable with the" flame spreader whereby to perniit of ready cleaning of these'parts.

Another object of the invention is to so -l0- cate the actuatingmember for the device that the same may be conveniently manipulated without likelihood of soiling or burning ones fingers. In the accompanying drawings: Figure 1 is a' view in front elevation of one end of a blue flame oil stove the burners of which are equipped with'the device embody'ing the present invention;

Fig. 5 is a fragmentary sectional View illustrating the character of the cleaning surface of the said cleaning member; s

Fig. 6 is a horizontal sectional view on the line 66 of Fig. 2 looking in a downward direction;

Fig. 7 is a vertical sectional view-taken substantially on the line77 of Fig. 13

Fig. 8 is a similar view taken substantially on the line 8'8 of Fig. 3. In the drawings the numeral 1 indicates a liquid fuel supply pipe, which pipe leads from the usual reservoir 2 and supports the burner. The burner is shown in detail in Fig. 2 of the drawings, and the same comprises the usual wick tube 3 having the inner and outer walls indicated respectively by the numerals 4 and 5. The wick .isindicated by the numeral 6 and is supported by the usual carrier 7 for vertical adjustment within the wick tube. Securedto theinner wall of the wick tube 4 is a bracket 8 whichextends below the lower end ofthe saidtube and has a portion 9 extending laterally and side of the liquid fuel supply pipe. 1, the

lower end of the portion 8 of the said bracket member being-designed to engage-the upper side of the said pipe .both as clearly shown in Figs. 2 and 8 of the drawing As is usual, the liquid fuel supply pipe 1. is provided with an outletin its upper side indicated by the numeral 11 and the wick tube 3 is provided at a point diametrically opposite the bracketmember 8-with anipple 12 having a passageway 13 communicating with the outlet 11 from the liquid fuel supply pipe. The nipple 12 has a down-turned end or branch 14: which isdesigned to seat in a liquid tight manner against a suitable boss 15 formed upon-the upper side of the pipe 1 and surrounding the outlet 11, and the saidnipple is clamped to-the pipe in a manner which will now'be explained. A yoke 16 com-prising spaced side members 17 and aconne'ctingmember- 18, is disposed to straddle the nipple l2 and the said pipe 1 and the lower endsofa the-side nembers 17 with a hookv portions. 19 with which-is engaged a link 20 designed to prevent spreading of these ends. -A clamping screw 21- is fitted through an opening22 formed in the connecting member 18 of the yoke 16 andis a d-justably threaded through a nut 23 whichlis confined bet-ween the side members 17 of the said yoke and, therefore, held against turning movement, thelower end of the screw 21 seatingin a suitable depression :24 formed in thetupperesideofthe nipple 12. Of course, by tighteningthe screw 21, the branch ltofthe nipple will, be firmly bound to the boss 15 so as to form a liquid-tight connection betweeir theseparts.

As is usual, the flame spreader, indicatedby thenumeral 125; is fixedly mounted in the upper 'end of the draft -t1ibe of the burner indicated by the numeral 26,the said draft tube beinfg provided at 5 its upper end with vertically extended spaced -po1'tions"27 having tongues 28.fitted through open'ing'sin the spreader 25 and' bent down to secure the spreader-fin place. The attachment'embedying" the present inventionincludes a cleaning member whiclrislc'learly illustrated :in Figs.'-21and 4' of-"th'e draivin gs, and this member which is "indicated*zin' general by tl1e,nun1era1-29,= includesan annular head "30 provided at its 'inner periphery With a depending -annula-r' fiange 31 which -fits-- rotatablyabout -theexterior of the upper end of the draft tube" 26, the said" head '30 being located between the upper end of the wick tube andthenn'der side of the'flame spreader 25. "A 'suitablespider 32 has the'end's or its armsfconnected to the head 30,*-*the said arms of 'thelspiderextending betweelr'the' spaced extended portions 27'of'the drait 'tube '26 and the" said'-:p0rtions 27 constituting, "by

The underside ofthe head 30' at the outer peripheral' "portion thereof constitutes 'the wick flcleaningasurface' and this portion of"'the underside i of *the head is provided with an inwardly extending horizontalflange 32' the underside ofwhich is serrated as indicated by the numeral 33, the serrations being'more or less Well definedas found-desirable.
